PROBLEM TO BE SOLVED: To solve the problem that a mere continuous operation of a blast fan from the start of platemaking to the end of plate loading by a reversing roller couple results in a plate loading jam due to mutual sticking of masters or the like and makes it impossible to surely prevent the plate loading jam and to obtain stable master transfer properties. SOLUTION: A control device 130 changes the timing of air blast of the blast fan 35 in platemaking and plate loading, based on an output signal relating to a copy size from either of a copy size detecting sensor 78 or 79 and a copy size setting key 116, an output signal relating to a paper size from either of a paper size detecting sensor 56 and a paper size setting key 115, an output signal relating to a platemaking image density from either of a platemaking image density detecting means 45 and a platemaking image density setting key 117 and an output signal relating to a working environment temperature from a temperature sensor 38.
